Simple bracket structure of back wall and construction method based on simple bracket structure of back wall

Abstract

The invention discloses a back-up wall simple support structure and a construction method based on the same. The back-up wall simple support structure comprises an abutment back-up wall, a plurality of steel tubes, a formwork, pre-embedded steel plates, triangular brackets, a square timber, I-beams and formwork brace pieces. The formwork is erected on the abutment back-up wall through the steel tubes, one ends of the I-beams are perpendicularly fixed to the abutment back-up wall, and the pre-embedded steel plates are arranged on the abutment back-up wall and located under the I-beams. One endsof the triangular brackets are fixed to the pre-embedded steel plates, the other ends of the triangular brackets are fixed to the bottoms of the I-beams, and the square timber is arranged on the I-beams. According to the construction method based on the back-up wall simple support structure, the construction progress is speeded up, the labor and mechanical inputs are saved, and the working efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of construction engineering, in particular to a simple back wall support structure and a construction method based on the back wall simple support structure. Background technique [0002] In the expansion project of Qingyin Expressway, the first application of liquid fly ash platform back construction technology has made a positive contribution to the improvement of project quality. nature, leading to a severe test in the construction cycle of the bridge abutment back. [0003] In the prior art, when constructing platform girders, most of them are constructed using the full-strut method. This method requires a better bearing capacity of the foundation under the bridge. It can be done manually, so there is no need for large-scale lifting equipment. At the same time, using this method to construct the cover beam will not have any impact on the appearance quality, but the disadvantages are that the s...
